Reaction of 3-(3-Arylpropenoyl)-2H-chromen-2-ones with Methyl 1-Bromocyclopentane-1-carboxylate and Zinc

Abstract

The reaction of 3-(3-arylpropenoyl)-2H-chromen-2-ones with methyl 1-bromocyclopentane-1-carboxylate and zinc resulted in the isolation, after hydrolysis of the reaction mixture, adducts of the Reformatsky reagent across the double bond of the heterocyclic fragment. The synthesized compounds exist in the enolic form.
